The Sun Hydraulics FRDBXAN (Material Number: FRDBXAN) is a 2-port restrictive flow control valve designed to fit into a 3-port cavity, with no connection to port 2. This valve requires the customer to specify a flow rating, and factory-set flow ratings are accurate within 10% of the requested setting. It is designed for applications where maximum pressure at port 3 should be limited to 3000 psi (210 bar). The sharp-edged orifice design minimizes flow variations due to viscosity changes, ensuring reliable performance across different fluid conditions. A tuneable adjustment control option allows up to a 25% variation from the nominal factory preset flow, with adjustments made using three turns of the adjust screw; turning clockwise increases the flow. The valve incorporates Sun's floating style construction, which minimizes the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. It fits into a T-2A cavity and belongs to Series 2, with a capacity of 12 gpm (45 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), and it can handle a maximum input flow of up to 30 gpm (120 L/min). The valve's hex size measures 1-1/8 inches (28.6 mm), and it requires an installation torque between 45 and 50 lbf-ft (61-68 Nm). The adjustment screw features an internal hex size of 5/32 inches (4 mm), while the locknut has a hex size of 9/16 inches (15 mm) and requires a torque between 80 and 90 lbf-in (9-10 Nm). The model weighs approximately .40 lb (.20 kg) and uses Viton seal kits for optimal sealing performance.
